The Quantum-Safe Sentinel #11 – September 2026
🇫🇷 🗞️ Au sommaire :
🚨 𝗟𝗮 𝗺𝗲𝗻𝗮𝗰𝗲 𝗾𝘂𝗮𝗻𝘁𝗶𝗾𝘂𝗲 𝘀𝗲 𝗽𝗿𝗲́𝗰𝗶𝘀𝗲, avec un plan pour casser les signatures derrière le Bitcoin.
🛡️ 𝗔𝘂 𝗻𝗶𝘃𝗲𝗮𝘂 𝗱𝗲 𝗹𝗮 𝗣𝗤𝗖, le G7 vous presse d'agir, et pas seulement sur la confidentialité : agissez aussi sur l'authentification !
⚛️ 𝗖𝗼̂𝘁𝗲́ 𝗰𝗼𝗺𝗺𝘂𝗻𝗶𝗰𝗮𝘁𝗶𝗼𝗻𝘀 𝗾𝘂𝗮𝗻𝘁𝗶𝗾𝘂𝗲𝘀, les projets spatiaux s'éloignent, mais ce qui se fait au sol n'a jamais été aussi concret.
💡 𝗦𝘂𝗷𝗲𝘁 𝗱𝗲 𝘀𝗲𝗻𝘀𝗶𝗯𝗶𝗹𝗶𝘀𝗮𝘁𝗶𝗼𝗻 : deux horloges, pas une. 𝙇𝙚 𝙃𝙉𝘿𝙇 𝙣𝙚 𝙧𝙚𝙥𝙧𝙚́𝙨𝙚𝙣𝙩𝙚 𝙦𝙪𝙚 𝙡𝙖 𝙢𝙤𝙞𝙩𝙞𝙚́ 𝙙𝙚 𝙡𝙖 𝙢𝙚𝙣𝙖𝙘𝙚 𝙦𝙪𝙖𝙣𝙩𝙞𝙦𝙪𝙚... Quelle est l'autre horloge qui tourne à toute vitesse selon vous ?
🇬🇧 🗞️ In the issue:
🚨 𝗧𝗵𝗲 𝗾𝘂𝗮𝗻𝘁𝘂𝗺 𝘁𝗵𝗿𝗲𝗮𝘁 𝗴𝗲𝘁𝘀 𝘀𝗽𝗲𝗰𝗶𝗳𝗶𝗰, with a blueprint for breaking the signatures behind Bitcoin.
🛡️ 𝗢𝗻 𝘁𝗵𝗲 𝗣𝗤𝗖 𝗳𝗿𝗼𝗻𝘁, the G7 is pushing you to act, and not only on confidentiality: act on authentication too!
⚛️ 𝗜𝗻 𝗾𝘂𝗮𝗻𝘁𝘂𝗺 𝗰𝗼𝗺𝗺𝘂𝗻𝗶𝗰𝗮𝘁𝗶𝗼𝗻𝘀, space projects keep drifting further out, but what is happening on the ground has never been more concrete.
💡 𝗔𝘄𝗮𝗿𝗲𝗻𝗲𝘀𝘀 𝗧𝗼𝗽𝗶𝗰: two clocks, not one. 𝙃𝙉𝘿𝙇 𝙞𝙨 𝙤𝙣𝙡𝙮 𝙝𝙖𝙡𝙛 𝙤𝙛 𝙩𝙝𝙚 𝙦𝙪𝙖𝙣𝙩𝙪𝙢 𝙩𝙝𝙧𝙚𝙖𝙩... so which other clock do you think is ticking at full speed?
The Quantum-Safe Sentinel #10 – July 2026
🏛️ This month, governments moved from advice to obligation. The US signed a pair of quantum executive orders, one to build the technology, one to defend against it, while new field data showed how far most systems still are from ready.
🛡️ In PQC, the deadlines are multiplying. A national agency, a financial regulator, a hyperscaler, and a standards body all set quantum clocks, and they are converging faster than many expected.
⚛️ In quantum communications, we look at a free platform for learning quantum security hands-on, a new experimental defense for QKD, and a European move to certify quantum-safe networks.
➡️ Our Awareness Topic goes deep on that QKD defense: how detection-efficiency-mismatch attacks work, and why a simple four-state countermeasure deserves to become standard.
The Quantum-Safe Sentinel #9 – June 2026
🗞️ In this June issue:
🏭 𝗤𝘂𝗮𝗻𝘁𝘂𝗺 𝗵𝗮𝗿𝗱𝘄𝗮𝗿𝗲 𝗶𝘀 𝗶𝗻𝗱𝘂𝘀𝘁𝗿𝗶𝗮𝗹𝗶𝘇𝗶𝗻𝗴.
🛡️ 𝗣𝗤𝗖 𝘀𝘁𝗮𝗻𝗱𝗮𝗿𝗱𝘀 𝗮𝗻𝗱 𝗺𝗶𝗴𝗿𝗮𝘁𝗶𝗼𝗻 𝘁𝗼𝗼𝗹𝗶𝗻𝗴 𝗺𝗮𝘁𝘂𝗿𝗲.
⚛️ 𝗤𝗞𝗗 𝗴𝗼𝗲𝘀 𝗻𝗮𝘁𝗶𝗼𝗻𝗮𝗹, 𝗰𝗼𝗺𝗺𝗲𝗿𝗰𝗶𝗮𝗹, 𝗮𝗻𝗱 𝗳𝗮𝘀𝘁𝗲𝗿. From Qatar to Malta to Sweden, deployments are leaving the lab.
💡 𝗔𝘄𝗮𝗿𝗲𝗻𝗲𝘀𝘀 𝗧𝗼𝗽𝗶𝗰: How to read a quantum hardware roadmap without being misled.

Why We Need Standardization of Quantum Key Distribution Networks
As quantum computing comes to the fore, many organizations are starting to plan their migration to innovative cryptography solutions. Adopting Quantum Key Distribution (QKD) is a good response to upcoming cyber threats related to communication. It necessitates standardized networks, and here’s why.
